Ultrasonic clothes dryer.

The researchers estimate the ultrasonic approach can dry clothes twice as fast as conventional dryers cutting drying times to about 20 minutes per load while using 70 percent less energy. While the ultrasonic clothes dryer is one of doe s more unique pieces of research standards and products developed by the agency have a significant impact on a wide range of products. Using aceee s logic. Unlike traditional dryers that rely on heat to evaporate the water out of clothes the ultrasonic dryer uses a completely different process that s less energy intensive.

Considering the thermal losses in the typical dryer even more energy is used for drying. Evaporation of water is a very energy intensive process which requires about 2200 kj kg 0 611 kwh kg of energy. When voltage is added the transducers vibrate at a. The ultrasonic dryer is three to five times more energy efficient than existing consumer options and it s able to dry full loads of laundry in 20 to 30 minutes versus the standard 40 to 60 minutes.

Heat is used to evaporate water. It works by using piezoelectric transducers a device that converts electricity to vibration. Taking care of your clothes. An ultrasonic clothes washer might sound like something from the future but the underlying technology is well established and has been in use for decades though it s more popular for cleaning rigid items like tools and optical gear.

Precommercial ultrasonic clothes dryer prototype with an equivalent energy factor ef higher than 5 4 lb kwh without increasing drying time by more than 20 over a baseline unit the primary energy savings technical potential will be 280 tbtu for the 2030 energy market in all climate zones this project supports the 2030 multi year program. Conventional dryers use heat to dry an article.
